Unverified85% confidenceDecision RuleTime unknown
HEPA滤网等级对照：H11过滤效率≥95%（PM2.5够用），H12≥99.5%，H13≥99.95%（医疗级）；家用空调加装选H11-H12即可，H13风阻过大反而影响空调运行

Unverified空调/新风机的HEPA过滤网选H11-H13级别即可满足家用除PM2.5需求，H13过滤效率≥99.95%，无需追求医疗级H14（阻力大幅增加会拖累风量和能耗）93% similarUnverified空气净化器HEPA滤网选H13级(过滤效率≥99.97%@0.3微米)即可满足家用防雾霾和过敏原，H14级(≥99.995%)主要用于实验室/医疗，家用溢价不值92% similarUnverifiedHEPA等级标准:H11过滤效率≥95%、H12≥99.5%、H13≥99.95%、H14≥99.995%。家用防雾霾H12-H13足够，H14过滤阻力大会显著降低风量并增加噪音91% similarUnverified空气净化器滤网优先认准HEPA等级：H13级对0.3微米颗粒过滤效率≥99.97%，H11级仅95%，雾霾/过敏人群应选H13及以上91% similarUnverifiedH13级HEPA滤芯的PM2.5过滤效率≥99.95%，H11级仅95%，对雾霾防护差异明显；但级别越高风阻越大，同CADR机型H13会更吵或更费电91% similar
